INTRODUCTION

As you know, in Texas, traffic accidents are something we witness almost every week or every day with our own eyes. However, it is not easy to witness aviation accidents and learn about them. For such a large block of metal to fly into the sky, humans must have put in a lot of effort. Therefore, we are curious what kind of impact and involvement people might have when something that big comes down.

DATA DESCRIPTION

Date: Date of accident, in the format - January 01, 2001

Operator: Airline or operator of the aircraft

AC Type: Aircraft type

Aboard: Total aboard (passengers / crew)

Passengers aboard : Passengers abroad

Crew aboard : Crew abroad

All fatalities : Total fatalities aboard (passengers / crew)

Passenger fatalities: Total Passenger fatalities

Crew fatalities: Total Crew fatalities

Ground: Total killed on the ground

Summary: Brief description of the accident and cause if known

DATA PREPARATION

When I look at the number of fatalities and the number of passenger aboard, I think that I could obtain the number of survivals by subtracting the number of fatalities from number of passengers aboard. Therefore, I subtract the values in the Fatalities column from the values in the Aboard column and then add those new values to my data set and name it Survival.

air = air %>% mutate(Survival = all_aboard - all_fatalities)

SUMMARY

Most of the time, when a plane crashed, passengers on board either mostly died or mostly survived. The survival rate of the passengers on board in 1908-2021 has been relatively low. However, deaths on the ground caused by plane crashes have almost never occurred. But once that happens, the plane crash had the potential to kill thousands of people on the ground like the 9/11 event. We also know that the three most dangerous countries to fly in are Russia, the United States, and Brazil. However, this might be suspected because those countries might have high air traffic so we cannot not conclude yet. In terms of the time of year to fly, the chances of being involved in a plane crash are fairly similar across all months and days of the year. On top of that, regardless of whether a person on a flight is a captain or a passenger, the chances of survival remain the same. The time with the most plane crashes is during the war and the type of plane involved in the most crashes (Douglas DC - 3) is the type used in the war. We have not found any commercial type of airplane that has an outstanding high number of crashes. In short, other than the time of war and the points we have not yet verified, air travel looks quite safe after 1999 to the present.
